我有一个登录 servlet,成功登录后,我希望用户
/登录/{用户名}/
如何username在 URL 中放置 POST 请求?
我已经查找了一些类似this和this的答案,但无法理解如何真正实现我的目标。我想坚持使用 servlet,避免使用 JAX-RS 等技术。
这是我的登录逻辑实现:
private void login_doIT(HttpServletRequest request, HttpServletResponse response) throws SQLException, InvalidKeySpecException, NoSuchAlgorithmException, ServletException, IOException {
String userInput = request.getParameter("user_name");
String pass = request.getParameter("pass");
pst = c.prepareStatement(query);
pst.setString(1,userInput);
rs = pst.executeQuery();
while (rs.next()){
imiya = rs.getString("user_name");
kyuch = rs.getString("key");
kodom = rs.getBytes("nitrate");
}
EncryptClass instance = new EncryptClass(2048,100000);
if(instance.chkPass(pass,kyuch,kodom) && imiya.equals(userInput)){
HttpSession session = request.getSession();
session.setAttribute("userLogged",userInput);
request.setAttribute("title",userInput);
String pathInfo = request.getPathInfo();
if(pathInfo!=null || !pathInfo.isEmpty()){
String[] pathArr = pathInfo.split("/");
String val = pathArr[1];//{username}
//now what??.....
}
request.getRequestDispatcher("/LoginLanding.jsp").forward(request,response);
} else {
request.setAttribute("message", message);
request.getRequestDispatcher("/index.jsp").include(request,response);
}
}
这是它的 web.xml:
<servlet>
<servlet-name>Login</servlet-name>
<servlet-class>AuthPack.ServletLogin</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Login</servlet-name>
<url-pattern>/Login/*</url-pattern>
</servlet-mapping>
在我提交表单后,URL 变成了类似
/登录
但我想要这样:
/登录/{用户名}
更优选:
/{用户名}
